Defines

#define DSP32_Q_CONVERT(x)   DSP32_Q((x)/2.)
 This macro is used to convert the raw data acording to the algorithm's optimization we need.

Variables

A_ALIGNED
TWIDDLE_FACTORS_PREFIX_TAB
dsp32_t 
dsp32_twiddle_factors [DSP32_N_TWIDDLE_FACTORS/2+2]
 This constant permits you to add attributes to the twiddle factors table.
It is useful if you want to store the table into another memory for example.
i.e.:.
A_ALIGNED
TWIDDLE_FACTORS_PREFIX_TAB
dsp32_t 
dsp32_twiddle_factors2 [DSP32_N_TWIDDLE_FACTORS]
